I think my marriage is falling apart. My wife has a bit of a temper and these days it seems like we are always fighting. I don’t want to fight anymore and I’ve explained to her that I can’t keep living like this. I used to love her but I’m not sure that I do anymore. I’m not sure if I ever loved her the way I should have loved her. She is so insecure, constantly looking over my shoulder, and blaming me for everything. I’ve told her so many times that she has to change or this won’t work. I’m not sure what to do except leave. Any advice?
